DIN17165 HII steel is mainly used to fabricate boiler and pressure vessel. So ,same the other boiler and pressure vessel using steel plate, this kind of steel has the good grain and mechanical properties. It's yield strength is between 185 to 265 MPa.HII tensile strength is from 90 MPa to 530 MPa. (different min strength point at the different thickness.)
